An oven is being used to bake cookies in this house. What energy transformations occur when baking cookies in this house?
a
heat energy → light energy → chemical energy
b
heat energy → chemical energy → light energy
c
heat energy → electrical energy → chemical energy
d
light energy → electrical energy → heat energy
The correct answer is: a) heat energy → light energy → chemical energy
The correct answer is: c) heat energy → electrical energy → chemical energy.
When baking cookies in this house, the oven converts electrical energy into heat energy. The heat energy is then transferred to the cookies, causing a chemical reaction that leads to their baking.
To answer this question, let's break it down step-by-step.
When baking cookies in an oven powered by solar panels, the energy transformations that occur are as follows:
1. The solar panels convert sunlight (light energy) into electrical energy.
2. The electrical energy powers the oven.
3. The oven converts electrical energy into heat energy, which is used to bake the cookies.
4. As the cookies bake, chemical reactions occur within the ingredients, such as the sugar and flour, resulting in the formation of chemical energy within the cookies.
5. Finally, when the cookies are removed from the oven, the heat energy is transferred from the cookies to the surrounding environment, which is air or room temperature.
Based on these energy transformations, the correct option is:
c) heat energy → electrical energy → chemical energy.
